Saint Ana Lake

Let yourself be charmed by the beauty created by a volcanic activity that began thousands of years ago and by the unique natural values concealed in this fairy tale land!

It is only here that you can discover the lake that was formed in an unaltered volcanic crater, the only one of its kind in Central and Eastern Europe, one of the most appreciated and visited tourist attractions in Székely Land. Saint Ana Lake is located at an altitude of 950 m in one of the twin craters of Ciomatu-Puturosu Massif (Harghita Mountains). 

The lake has an almost circular shape, similar to a painter’s palette, it is 620 m long and 460 m wide at its largest point, it has an area of 19.5 ha and a maximum depth of 7 m. The lake fills only with precipitations, as it has no spring. The purity of the water is close to that of distilled water, with only 0.0029 ml minerals. The low trophic capacity of the lake water is also due to the mofetta discharge through the bottom of the lake and the walls of the crater.

Tourists who come to Saint Ana Lake do not need weather forecast to see what the weather will be like, as they can use an empirical, yet accurate method, provided by the volcanic mountain: the two fissures formed in the mountain can predict the weather. Locals know that “if the discharge from the fissures has a biting smell, a storm will come; otherwise, the day will be sunny, perfect for trekking”. The phenomenon has a scientific explanation. A post-volcanic activity still occurs inside the mountain, sensitive to any change in atmospheric pressure. When the atmospheric pressure drops, gas such as carbon dioxide and sulphur rise to the surface and flood the fissures with a sharp, biting smell, a sign of rain. 

On the shore of the lake you will also find the Roman Catholic Chapel whose patron saint in Saint Ana, and which has been built and maintained by the local community of the village of Lăzărești. 

When you reached the lake, you may have noticed you are in a protected natural area, managed by custodians, so please respect the visitation rules, leave nothing but your footprints behind and take nothing but memories with you :).

We invite you to discover our Narnia, Tinovul Mohoș, which is close to the lake, at an altitude of 1050 m. It is one of the most valuable protected natural areas in Romania, famous mostly due to its glacial relict plants and its vegetation, specific to peat-bogs. 

The star of the reserve is the carnivorous plant called round-leaved sundew, but other equally beautiful, interesting species are sedge, bog-rosemary, lugalaria or hare’s-tail cottongrass. Since the entire vegetation is basically a layer of peat formed over a lake, all plants inside the oligotrophic bog have adapted, providing the perfect environment for forest vegetation consisting of Scots pine, dwarf birch and downy birch.

We will not tell you more, we’ll let you discover it yourself, but you should know that the reserve can only be visited with a guide. Look for the custodian and you will learn everything you need to know about how the oligotrophic bog was formed and the rare species hidden in this fairy tale land
